I have updated to version 1884. I have 3 shared folders with my MAX OS X, where I put all my development files (source code, ...) and I shared code with WinXP. Now, when I begin to work with that files, the VM disconnected from the shared folders (the contents of the shared folders dissapears), and I see that all opened files was deleted from the original folders (they were opened as read-only!!!) Be careful!!!
